    Z, Wenyi

    Dr Santana and her staff are very professional and excellent explaining all the possible treatments for my dental needs. Did not have to wait for my appointment. Astra Dental is a great Dental Clinic in North York, near Yonge and Finch intersection and near the Subway Station so very easy to get there by public transit. I will highly recommend Astra Dental to all my friends in North York and Toronto area.

    Astra Dental has a new Dentist and she is amazing. The whole office looks nicer now.
    I took my kid and he had a great experience. Dr. Santana took the time to explain every step and although he was nervous at first, then he was fine. The tv in the room is a big plus. I will recommend this place.
